how does the fix_error_editor hook work?


Hi,

I am trying to integrate ipython am gvim (see my previous post).
I discovered this: http://projects.scipy.org/ipython/ipython/wiki/CookBook,
section "Using gvim in server mode"

I copied the code, and the "fix_error_editor" function works. But when is it
called?
It is not called on syntax error here ...

Any advice?

Thanks!
Nathan

Hi,

well that is cool!
This way I can send code from gvim to ipython, very nice.

But how can tell ipython to tell gvim to go to the current line when an
error occurs in pdb?

Can I somehow tell ipython to execute some action on every pdb error and
breakpoint?


Sorry, I am not very experienced in this matter. I tried once to integrate IPython and GVIM, especially before the SciPy09 conference time. These two are my main dev environment, they are just not connected. If I seriously need to use a debugger, I use Eclipse+PyDev. Otherwise I just use traditional way of debugging using simple print statements.

Paul Ivanov from UC Berkeley has more to say on this subject.

Good luck.

 
Thanks!
Nathan

Printing breakpoint list

Hi,

Is it somehow possible in ipython/pdb to print a list of the current
breakpoints into a file?

Regards,
Nathan

how to restore %store-ed variable without restarting IPython?

I save a variable by doing

In[10]: %store f

and then I later change it interactively, but I want to return to the
original version. Is there a

In[11]: %reload f

to do that?

Thanks!

Use the "break" command (with no arguments) inside the debugger.
http://docs.python.org/library/pdb.html#debugger-commands

Hope this helps,

Hi,

Tanks for the answer, but how do I know store the output of "break" into
a file (or first into a variable)?

I also discovered:
pdb.Pdb.get_all_breaks()

But it just gives me:
*** TypeError: unbound method get_all_breaks() must be called with Pdb
instance as first argument (got nothing instead)

Thanks!
Nathan

Ah, I'm sorry...I parsed your question as "print (a list of the current 
(breakpoints into a file))"... 8-)

When would you ever want to print breakpoints to a file? If you're using pdb 
programmatically to set breakpoints, you will already have access to a pdb 
instance (created with p = pdb.Pdb()). Then p.breaks is a dict of the current 
breakpoints. Otherwise, you're using the interactive debugger and can just copy 
output from the command window. Or am I missing something here?

> I also discovered:

Yes:

In [39]: pdb.Pdb.get_all_breaks??
[...]
Source:
    def get_all_breaks(self):
        return self.breaks

> But it just gives me:

> instance as first argument (got nothing instead)

Yes, pdb.Pdb is just a class, you need to instantiate it with Pdb(). This 
works, kind of:
>>> pdb.Pdb().get_all_breaks()
{}

Marginally more usefully:
>>> p = pdb.Pdb()
>>> # add some breakpoints (but how?)
>>> p.get_all_breaks()

I think this feature request, "expose IPython's pdb instance", may be 
sympathetic to your cause.

Maybe the __IP.InteractiveTB.pdb.get_all_breaks() hack could be useful to you.

That is exactly what I was looking for! Thanks a lot!

autcompletion and trailing space

Hi,

When I do autocompletion (tab) in ipython and it completes a complete
function (or something else) it always adds a trailing space. Most of
the times I have to hit backspace, because I want to type "(" or "."
directly behind the completet name.

Can the trailing space be disabled?

Thanks!
